CONCRETE TILE FOR BUILDING CONSTRUCTION.

. Specification of Letters Patent.

Application filed December 21, 1916. Serial No. 138,247.

To all whom it may concern: 7

Be it known that I, LEANDER DOUGLAS HARTEB, acitizen of the United States, residing at Oklahoma, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Concrete Tiles for Building Construction;

and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in concrete tiles for building construction and more particularly to the locking means for securing the tiles together.

The object of the invention is to provide a simply constructed device for locking the adjacent ends of two tiles together and forming a tight joint between them.

Another object is to provide an improved corner tile so constructed as to render it very strong and yet which may be cheaply made and be entirely sanitary, affording no edges for lodgment of dirt.

Another object is to provide improved side bars with ventilating means. K

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described andclaimed, it being understood that changes in ;the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings:

The concrete tile illustrated as an embodiment of this invention which is made of suitable and customary material molded in a machine for the purpose, includes 2. rectangular metallic frame made of channel iron and T-bars. The end members 20f the frame are constructed of T-bars' with the heads thereofprojecting outwardly while its side members 3 are. of channel iron with their concave faces disposed outwardly. These end and side members 2 and 3 are united by forming tenons 4 on the ends of the end 'members' 2 which are inserted in v apertures '5 formed in the cross bars or intermediate portions 3* of the channel iron side 8 which are inserted in apertures in the, channel irons and which are set in the tile when molding, it being of course understoodthat thetilebodies are molded around the reinforcing means. i

' The hannel irons 3 'which form the side members oftheframe are madeflof different widths, the-larger" adapted to fit over terlocked and displacement of the tiles pre-- vented.

The heads 2 of the Ts 2 which project from the ends of the tiles are connected by channel irons 9, two being employed to connect the meeting ends of a pair of tiles. One of\these connecting channel irons 9 spans the flanges at one side of adjacent T-heads and the other similarly spans those on the other side of said heads as is shown clearly in Figs. 6 and 9. Bolts 10 extend through the intermediate or cross bars 9 of the irons 9 between the heads of the Ts 2 and securely clamp them together, forming a rigid connection which prevents any tendency of the wall to buckle or sway laterally.

In Figs. 10 to 13 another form of end connection for the tiles is shown, the structure of the tiles being otherwise the same. In this form, the Ts of the other form are replaced by fiat bars 12 which are connected to the side channel bars 3 in the same way as the Ts 2. The free ends of the flat bars 12 of adjacent tiles are arranged in overstrength of the tile also renders it sanitary as the rounded-inner corner will not catch and hold dirt. These tiles 14 have right angular channel bars 17 on theopposed side faces thereof which have cross braces 18,

and avoids all possibility D of the building crackin at the corners.

Ventilators 19 are arranged in some of the tiles and as shown in Fig. 15, e ch is constructed in the form 'of a meta tube 20 which is set in the tile when molding, being held in place by cement. This tube is set at an angle of about 415, the higher end being disposed on the inside of the wall when the tiles are in use, so as to prevent the entrance of rain and snow through the ventilaton A removable tube 21 is made to fit in tube 20, being provided with a screen 22 and a flange 23 to prevent it from slipping through the stationary tube 20. The tube 21- is made removable to facilitate repairing of the screen, and the ventilator may be closed by a slide 24. This yentilatoris especially useful for ventilating and fumigating grain bins to destroy weevil and other insects. When used as a fumigator, the insect exterminator or disinfectant is placedcent blocks.

end portions of said bars bin and having a closure 26, the disinfectant being replenished when deslred. When used as a ventilator only the disinfectant container is removedk These improved tiles are preferably provided with lath attaching means shown in Figs. 1 to 12 in ,the form of tie wires 27 These thick, thereby greatly cheapening the construction of a building. These improved tiles may be made of any desired width and length, being preferably made two feet wide an of any desired length. The use of these tiles also insures material.

I claim: I

1. A plastic building block having a air oftransversely extending reinforcing ars molded in its ends and extending beyond the same for attachment to similar bars of other blocks, and longitudinal bars extending along the opposite sides of said block and secured at their ends to the ends of said transverse bars.

2-. A plastic building block having channel bars extending along its opposite sides with their flanges disposed outwardly, and transverse bars secured to said channel bars and embedded in the ends of said block to retain said channel bars in place, said trans great economy in labor and verse bars extending-beyond said ends of the block to provide means for connecting adja- 3. A plastic building block having channel bars extending along its opposite sides with their flangesprojecting outwardly, the aving openings formedtherethrough, and transverse bars molded in the ends of said block and having tenonsextending through said openings and clenched upon said channel bars, said transverse bars extending beyond the ends of said block to form means for attaching adjacent blocks. i i

In testimony whereof I have hereunto set my hand in the presence of two subscribing wltnesses.
